Key Performance Advantages:
- Precision Steering Response: The angular contact design is optimized to handle combined radial and axial loads simultaneously, ensuring the steering stem remains stable and fluid during cornering and braking maneuvers.
- Specialized Asymmetrical Geometry: With a 10.95 mm inner ring and a slim 6 mm outer ring, this bearing is a direct fit for OE steering head housings on Honda and Yamaha motorcycles, ensuring perfect alignment without modification.
- Enhanced Durability: Manufactured to withstand the constant impact and vibration of road use, the internal raceways are precision-ground to minimize friction and prevent "notchy" steering feel over time.
- Optimized Load Distribution: The contact angle is specifically tuned for steering applications, providing high axial rigidity to maintain the rake and trail geometry of the motorcycle under heavy front-end load.
- High-Grade Material Construction: Built using premium bearing steel to ensure long-term resistance to surface fatigue and wear, even in exposed steering head environments.
